DriverData (ONOS Java API (2.7.0))

All Superinterfaces:

Annotations, MutableAnnotations

All Known Implementing Classes:

AbstractProjectableModel.AnnotationDriverData, DefaultDevice.DeviceDriverData, DefaultDriverData
```
public interface DriverData
extends MutableAnnotations
```
Container for data about an entity, e.g. device, link. Data is stored using MutableAnnotations. Note that only derivatives of HandlerBehaviour can expect mutability from the backing driver data instance; other behaviours must rely on immutable Annotations only.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default <T extends Behaviour> T`	`behaviour(Class<T> behaviourClass)`	Returns the specified facet of behaviour to access the device data.
`DeviceId`	`deviceId()`	Returns the device identifier.
`Driver`	`driver()`	Returns the parent device driver.

- Method Detail
  - driver
```
Driver driver()
```
    Returns the parent device driver.
    
    Returns:
    
    device driver
  - deviceId
```
DeviceId deviceId()
```
    Returns the device identifier.
    
    Returns:
    
    device identifier
  - behaviour
```
default <T extends Behaviour> T behaviour(Class<T> behaviourClass)
```
    Returns the specified facet of behaviour to access the device data. Implementations are expected to defer to the backing driver for creation of the requested behaviour.
    
    Type Parameters:
    
    T - type of behaviour
    
    Parameters:
    
    behaviourClass - behaviour class
    
    Returns:
    
    requested behaviour or null if not supported
